Isaiah 1:3

“The ox knoweth his owner, &c.] Knows his voice, when he calls him, and follows him where he leads him, whether to plough in the field, or feed in the meadows; and the ass his masters crib, or “manger”; where he is fed, and to which he goes when he wants food, and at the usual times. Gussetiusf21 interprets the words; the ass knows the floor where he treads out the corn, and willingly goes to it, though it is to labour, as well as to eat; and so puts Israel to shame, who were weary of the worship of God in the temple, where spiritual food was provided for them, but chose not to go for it, because of labour there. [But] Israel doth not know; his Maker and Owner, his King, Lord, and Master, his…”

“(Jer 8:7). crib--the stall where it is fed (Pro 14:4). Spiritually the word and ordinances. Israel--The whole nation, Judah as well as Israel, in the restricted sense. God regards His covenant-people in their designed unity. not know--namely, his Owner, as the parallelism requires; that is, not recognize Him as such (Exo 19:5, equivalent to "my people," Joh 1:10-11). consider--attend to his Master (Isa 41:8), notwithstanding the spiritual food which He provides (answering to "crib" in the parallel clause).”

“The ox ... - The design of this comparison is to show the great stupidity and ingratitude of the Jews. Even the least sagacious and most stupid of the animals, destitute as they are of reason and conscience, evince knowledge anal submission far more than the professed people of God. The ox is a well known domestic animal, remarkable for patient willingness to toil, and for submission to his owner. Knoweth his owner - Recognizes, or is submissive to him. The ass - A well known animal, proverbial for dulness and stupidity. His master’s crib - אבוס 'êbûs from אבס 'âbas, to heap up, and then to fatten. Hence, it is applied to the stall, barn, or crib, where cattle are fed, or made fat; Job…”

“Know - Me their owner and master. Knowing is here taken practically, as it is usually in scripture, and includes reverence and obedience. Isaiah 1:4”

“1:3 an ox knows its owner: Not so with Judah. Yet despite their rebellion, God still graciously addressed them as my people.”

“ox: Pro 6:6; Jer 8:7 but Israel: Isa 5:12, Isa 27:11, Isa 44:18; Deu 32:28, Deu 32:29; Psa 94:8; Jer 4:22, Jer 9:3-6, Jer 10:8, Jer 10:14; Mat 13:13-15, Mat 13:19; Rom 1:28; Pe2 3:5 Isaiah 1:4”

“Jehovah then complains that the rebellion with which His children have rewarded Him is not only inhuman, but even worse than that of the brutes: "An ox knoweth its owner, and an ass its master's crib: Israel doth not know, my people doth not consider." An ox has a certain knowledge of its buyer and owner, to whom it willingly submits; and an ass has at least a knowledge of the crib of its master (the noun for "master" is in the plural: this is not to be understood in a numerical, but in an amplifying sense, "the authority over it," as in Exo 21:29 : vid., Ges. 108, 2, b, and Dietrich's Heb. Gram. p. 45), i.e., it knows that it is its master who fills its crib or manger with fodder (evus, the…”
